. Application filed-May 26;

This invention relates to a: faucet of the generaltype usedin dispensing liquids from a tank, oroth'ersource of supply, more particularly where the liquid is dispensed intosometimes fails to retain the drops and is sired. j l V r V 5 V The ob ect of myapresent invention 1s to improvesa'id prior construction as to make therefore not as perfectly effective as is dethe drip, or preventing any dropsfrom falling from the faucet afterthe valve has been seated; p 8 i v I accomplish these objects by means of '*the constructionhereinafter described and as illustrated inthe accompanyingidrawing lnwhichz 1 V F ig. 1 is a vertical longitudinal sectional V view'of a faucet'embodying. my invention.

Fig. 2. is a side elevation andFigf isa plan view thereof.

Fig. 4- Fig. 2. r Fig.

portionof the faucet'and i Fig. 6, is a bottom planHview 'of-the dis charge end; 1 l 1 As shown in the drawing, vthe-faucet-casing comprises a horizontal inlet portion a,

adapted to be connecteditothe source of suppl'yand opening into a vertically extendnig valve chamber 5, which is closed'atits upper end and has a'cylindricallyi shai'ned tubular,

outlet portion-c removably connected-thereto, to permit assembling, and depending" vertically therefrom, so as to form a continnation of the chambers Thealower"portion of the wall of said outlet portion:cistapered inwardly, as it extendsdownward, forming an upwardly facing valve seat e, from which anfannul'ar hp portion f depends, the 111- ternal surface thereof extending from =tl1'e valve seat portion at a; substantiallyreduced angle of convergence and the edge of said lip being disposed. inahorizontal plane. A valve stem g is provided havlng an internal bore which extends flOHlltS upper end and is a sectional view at line fla l of I is a sectional View similar to Fig.- l, onan enlarged scale, ofthe discharge 1926.] Serial n6; 111572;

in Whicha guiding post'h is arranged,said

post being fixed in the top side' of the chain--. 5 her 6, and depending vertically.therefrom;

so that said stein wvillg' be vertically guided on said post. A flange c' is formed on the upper end ofthe stem and acoiled spring j is arranged on said post andinterposed between the upper" side of chamber b and flange i. I The lower end offt'he stem g is, provided with a head having an" annul'arx groove therein in which an elasticv'alve \vasher'k" is held in position; to be pressed against the seatebyjthe' spring -T he' eX -I a. i

treme lower vend-portion ot'bt'he stem is formed to provide a cylindrically shaped projection m,'whichdepends below-the level" I of the-Washer 7c and forms aclosure' for the upper end of the space enclosed by the lip fIwhen; the valve ne ated. The diameter" of 'the projection m is somewhatless thanthe internal diameter of the lipportion ad jacentv the seat '6, but greater than this internal diameter at the lower end of theilipi portion, the:'arra11geme11t being such that the lower end of-t'h'e projection is held in close proximity to theinner'surface of the lip' portion- Whenthe valve is seated, without actually .engagingsaid surface,- so as to" prevent full action" of the spring in pressing .the valve washer against its seat, sufficient leeway, in this respect, being 'providedfor yielding and wear of the washer. i;

' lVith this construction, therefore, a shal lowi recess Will' be formed at the extreme lower end of the faucet outlet, the topof which is flat and disposed in a horizontal plane, and the sides of whichiare' undercut,

or'extend' downward therefrom at a slight convergence. r

A handle Wis provided for lifting the valve-fronrits seat'; said handle being .connected at right angles to a shaft 0, rotatably mounted in a-packing nut 13in one side: of

the inlet portion a, said shaft having a right angularlyextending arm Q atits inner end arranged 'to engage. the under. side of the flange i,so that when the handle is-pushed rearward-the valve will be lifted from its seat.

The operation is as follows: Whenthe valve has been: opened, so that the liquid flows fromthe outlet, and then is permitted I to be reseated so that the flow pastthe seat is cut ofttheigreater portion: of" the liquid remaining in the recess enclosed by the-lip f will lye-discharged with the solid stream.

A large drop will, however, usually be re tained in said recess, which will remain suspended froin the flat under slde of the proeet-ion m, as indicated in Fig. 5, or may be partly supported by the convergingsides of the lip. It is considered that the drop will be primarily supported by the capillary attraction of the relatively large flat'horlzontal surface of the projection m, and also more effective than the construction of my said prior application.

Iclaun: V 1. In a liquid dispensing faucet, a depending tubular casing having a discharge port ranged that, when the valveis sea-ted, its edge will beheld 1n closeproxnnity to theing tubular easing having a discharge port at its lowerend, the walls of which terminate at a uniform level, said casing being; internally constricted 'toform an upwardly facing valve seat and constructed to provide a relatively;short annular lip depending from 5 said seat and forming the lower end portion ofthe casing-,and a valve vertically movable in said casing toengage said seat and hav Sing a :flat, circular, horizontally disposed drop-sustaining face at its lower end ar ranged, when the valve is seated, to effect a sutiiciently tight closure ofthe top portion of the space encircled by said lip, at a level slightly above the level of the edge of the lip,

to form ashallow recess adapted to retain iuidischarged drops of liquid which have passed the valve seat. 7 v
